Example Embodiment

[0024] Embodiment: The method for group call merging in a Virtual Chassis switching center of this embodiment includes the following steps:

[0025] After the group call controller establishes the session C1 of group A according to the group call request initiated by the user terminal, if some other switching center establishes the session C2 of group A according to the group call request initiated by the user terminal and sends the group A session C2 The call request is sent to the group call controller. The group call controller stores the information of session C2 in the session record information table of group A, allocates resources to the call request, converges the media of session C1 and session C2, and sends the call request to the exchange The center reply incorporates success information;

[0026] When the user terminal of the session C1 initiates a PTT application for speech, the user terminal applying for the speech sends a speech request to the group call controller. ...

Abstract

The present invention discloses a cluster switching center group call and incorporating method and a conflict resolving method. The incorporating method comprises the steps that after a group call controller establishes a session C1 of a group A according to a group call request initiated by a user terminal, if a switching center establishes a session C2 of the group A according to the group call request initiated by the user terminal and sends a call request for the group A to the group call controller, the group call controller stores information of the session C2 in a session record information table of the group A, allocates resources to the call request, aggregates media of the session C1 and the session C2, returns incorporation success information to the switching center that sends the call request. According to the cluster switching center group call and incorporating method and the conflict resolving method disclosed by the present invention, the sessions of a plurality of switching centers of a same group call can be merged, thereby ensuring smooth emergency command communication.

Description

technical field [0001] The invention relates to the technical field of trunking communication, in particular to a group call merging method of a trunking switching center and a conflict resolution method. Background technique [0002] The trunking communication system is an advanced mobile dispatching system, which represents the development direction of the dedicated mobile communication network, one of the communication systems. The trunking communication system has the function of sharing available channels for all users of the system and automatically selecting channels. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing costs, and sharing channel equipment and services. Because the digital trunking communication system has the advantages of large system capacity, high frequency utilization rate, and various functions, it has become the mainstream technology in the field of trunking communication. [0003] ...
